15% of registered voters have already voted and Romney is up by 6% among them.

Fifteen percent of registered voters nationwide have already cast their ballots in this year’s election, according to Gallup Daily tracking for the week ending Oct. 28. That is up sharply from 5% a week earlier. The overall percentage either having already voted or planning to vote before Election Day has also increased – to 33%, from roughly 25% in each of the prior three weeks.

What would be interesting to see is where these people have voted. If it’s all people in Texas and Mississippi who have voted early for Romney it’s useless. He needs people in Ohio, Nevada, New Hampshire, etc voting early for him.
